40% of all electricity is used by turned off devices

From New York Times
The Department of Energy estimates that in the average home, 40 percent of all electricity used to power home electronics is consumed while the products are turned off. Add that all up, and it equals the annual output of 17 power plants, the government says.I started checking how much electricity my electronics were consuming when I wasn’t using them. I used a Kill A Watt EZ energy meter (available online for about $25) and began measuring. My PC was continuously drawing 134 watts all night.
The more devices I checked, the worse it got. My TiVo digital video recorder was sucking down about 30 watts when it was not playing or recording a show. A Comcast digital cable set-top box made by Motorola that I tested was drawing about 40 watts. My DVD player was drawing 26 watts while idle, and my audio system — which I rarely turned off — was using 47 watts. This was in addition to the numerous power adapters and chargers, each drawing 1 or 2 watts, not to mention several other devices sipping energy to keep clocks running or to be ready to turn on at the push of a button.
I am completely guilty!

This is amazing. I always thought that when my PC was off, it was only drawing a few watts… to power an LED on my mobo, and a few other things. Apparently, I was wrong. I’ll be sure to flip that switch on the surge suppressor before I go to bed, on all of my electronics, now.
Sheesh! People need to be made more aware of this.

I agree, this is crazy. Inspired me to create OffShouldMeanOff, which is a database of these power ratings (when the devices are off).
The world needs to know about this!
